For example, a method of mixing two resins, A and B, which are resins having inconsistent chemical structures, into three layers, and mixing the two resins A and B to form an interface will be described. In other words, when the three resin layers are sequentially turned into the first layer, the second layer, and the third layer from the material side, in order to form the first resin layer, two resins A and B are prepared in advance with A / B = R i 2 X i / Y i mixed resin film. Similarly, the mixing ratio of the two resins A and B forming the resin film of the second resin layer is R 2 = X 2 / Y 2 and the mixing of the two resins A and B forming the resin film for the third resin layer The ratio is R 3 = X 3 / Y 3. At this time, since the resins A and B are contained in the first to third resin films, these resins are compatible with each other, and the interfaces of these resin layers are relatively easy to be integrated. In addition, when the numbers 混合 of the mixing ratios R1, R2, and R3 of the resins A and B are as close as possible, the interfaces of these resin layers are more easily integrated.

Only the resin layer of the middle layer is composed of different resin layers. The base resin of each of these layers can be appropriately selected according to the purpose of each layer. For example, the base resin constituting the resin layer in direct contact with the aluminum foil and the aluminum foil are preferred, and the base resin constituting the uppermost layer has corrosion resistance and chemical resistance Good sex is better. When the resin layer of the present invention is three layers, the ideal thickness of the resin layer: the thickness of the first resin layer on the substrate side is 0.5 to 20 microns, and the second resin layer is formed on the first resin layer The thickness is 5 to 150 micrometers, and the thickness of the third resin layer formed on the second resin layer is 0.5 to 150 micrometers. The reason is that if the thickness of the first resin layer is less than 0.5 μm, it is difficult for the resin layer to completely cover the surface of the substrate, so the adhesion between the substrate and the first resin layer is insufficient, and the first resin layer is easily removed from the substrate. When the substrate is peeled off, if it exceeds 20 micrometers, the adhesiveness with the substrate is saturated and the economy is affected. In addition, if the thickness of the second resin layer is less than 5 micrometers, color unevenness is easy to occur, or discoloration is easy to occur during processing such as forming processing. If it exceeds 120 micrometers, the internal stress of the resin layer is excessive when curing, This resin layer is prone to cracks or peeling, or it is prone to processing and adhesion (please read the precautions on the back before filling this page)-The size of the paper is bound to the Chinese National Standard (CNS) A4 (210X 297) -15) -15- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1224555 M —___ B7 V. Description of the invention (13) Deterioration (adhesion after processing such as forming processing) is reduced. In addition, if the thickness of the third resin layer is less than 0.5 μm, it is difficult to completely prevent the pinholes in the resin layer that are unavoidable, and there is a concern that the protection function cannot be fully exerted. Saturation affects economics. In addition, the thickness of the resin layer when the resin layer is two in the present invention refers to the thickness of the first resin layer and the thickness of the second resin layer when the foregoing resin layer is three. "Laminating method of resin layer" As a method of forming the resin layer of the aluminum foil of the laminated laminated film of the present invention, a conventionally known coating method of various metal plates or a method of laminating to form a resin layer can be used. When the resin layer is formed by the coating method in the present invention, the resin can be coated on Jinfan A by a roll coater, etc., dried to form a coating film, and then another coating film is also formed on this coating film to form two layers. Or a three-layer laminated structure. In this case, the aforementioned drying step may be omitted if necessary. In addition, when the aforementioned resin film laminated resin is pasted on the aluminum foil A one by one, the adhesive layer at the interface of the resin layer is not particularly limited, as long as the heat treatment performed when the interface of the resin layer is integrated, it will not hinder the resin layer. Characteristic can be. In addition, the resin layer is not provided, and the resin layers are adhered to each other by thermocompression bonding or the like, and the resin layers are combined into two or three layers. In addition, the aluminum foil of the laminated laminated film of the present invention can simultaneously form multiple (two or three) different resins that are compatible with each other into a film state, and perform lamination by co-extrusion. The laminated film was covered with aluminum foil by sticking. The principle of this co-extrusion method is shown in Figure 8.

The depth distribution of the T i signal intensity with a linear relationship between the T i atom concentration (the change in the T i signal intensity in the depth direction of the resin layer) is a graph of the results. In Fig. 2, the horizontal axis represents the depth from the outermost surface of the resin layer L1, and the vertical axis represents the intensity of the EPMA signal of the Ti atom in the colored pigment τi〇2 in the resin layer L1. As shown in FIG. 2, the depth distribution of the signal intensity of the T i atom in the resin layer L 1 has a peak in the resin layer 2 and is continuously distributed with the resin layer 1 and the resin layer 3. When the resin layer L 1 of the aluminum foil M 1 of the laminated film was lifted off from the aluminum foil A, J H ′ When the interface state of the cross section of the resin layer L 1 was observed with an optical microscope ′, no boundary between the resin layers was found at all. From this result, it can be confirmed that the interface between the resin layers of the aluminum foil M 1 of the laminated laminated film of the present invention is integrated.

Description of the Invention (19) The surface treatment of Mingbo is degreased and strip-washed, and then the surface of the aluminum foil is applied to improve the corrosion resistance of aluminum foil A or the adhesion with the resin layer. Chemical transformation commonly used in processing. Then, the paint containing the predetermined resin is coated on the case A with a conventionally known applicator coating, brush coating, or the like, or a predetermined resin film made by a co-extrusion method is pasted on the aluminum foil A, or After a plurality of resins are thermally dissolved, a mixed polymer mixed in a predetermined ratio is continuously projected on the surface of aluminum foil A in a film shape, and the resin layer is laminated into three layers by lamination. Alternatively, the resin layer can be synthesized into three layers one by one on any substrate, and then a previously formed resin film is laminated on the aluminum foil A. At this time, in the three-layer resin layer, when the coloring pigment is added only to the intermediate layer resin layer, the step of adding the coloring pigment to other resin layers can be omitted, and at the same time, the step of integrally forming the interface between the resin layers is followed by the coloring pigment. Thermal diffusion from the middle layer to the upper and lower layers, as shown in Figure 2, the colored pigment has a continuous concentration distribution in the three resin layers. In addition, the aluminum foil A having the laminated resin layer is heated to a temperature range above the melting point of each of the resin layers and below the decomposition point, and then heat-treated. Thus, the aluminum foil M1 of the laminated film of the present invention can be obtained.
